Analysis Of Newton Raphson Load Flow Method With Wind Power

​The main purpose of the wind energy is to create energy source which is pollution free and come with a reasonable price. The wind energy used in wind turbines are increasing their demand and becoming popular in the green energy world. Since the rebirth or rapid growth of wind energy took place from early 1980. The growth of the industry has been more than expectations. As all the good things the wind energy poses certain negative impacts of having high maintainer cost. Repair and data collection should be monitored regularly of the turbine to get the idea of placing a new wind energy plant or to maintain the old one. This paper explains the modeling of Wind Energy Conversion Systems and their technologies which is used for the generation of wind power and control strategies of the conversion system.

A Novel Modeling & Design of STATCOM with Controllable grid connected Variable Speed Wind Energy Supply System

The unscented transformation (UT) method is applied in order to study the optimal probabilistic load flow analysis under the uncertainty of wind farms [5]. The modifications of Point Estimated Method (PEM) are utilized to solve O-PLF in power network equipped with wind turbines (WTs) and photovoltaic (PV) systems [12]. Also, 3-PEM is used for PV source with Electric Vehicles (EVs) application [13].

Abstract—This paper investigates the optimal active and reactive power control capabilities for typical wind turbine (WT) driven doubly fed induction generator (DFIG). The main objective is to determine the optimal rotor voltage to extract certain active and reactive power from the DFIG over wide ranges of wind speed. Teaching Learning Based Optimization (TLBO) algorithm is a new heuristic optimization technique, used to obtain the optimum rotor voltages to achieve reference active and reactive powers overall operating points. Artificial Neural Network (ANN) controller is used as an adaptive controller to predict the value of rotor voltage for all operating points. The ideal power curve of a 2 MW wind turbine has been estimated to design the active power controller. The stator reactive power control capability with the range of ±1.6 MVAR is developed. With the proposed control strategy, the DFIG-based wind farm provides Maximum Power Point Tracking (MPPT), fully active and reactive powers control. For all operated wind speeds, the adaptive proposed controller develops useful network

Abstract—This paper presents a voltage and frequency control of wind-hydro hybrid system in isolated locations in which one squirrel cage induction generator (SCIG) driven by a variable speed wind turbine and another SCIG driven by a constant power hydro turbine feeding three phase four wire local loads. The system mainly uses a rectifier and a pulse width modulation controlled insulated-gate-bipolar-transistor-based voltage-source converters (VSCs) with a battery energy storage system at their dc link. The main objectives of the rectifier is to convert the ac power generated by the wind system to dc and the control algorithm for the VSC is the control of the magnitude and the frequency of the load voltage. This system has the capability of bidirectional active- and reactive-power flow, by which it controls the magnitude and the frequency of the load voltage. Here pitch angle control is used to achieve maximum power tracking(MPT).In this paper wind turbine, hydro turbine, MPT controller, and a voltage and frequency controller are modeled and simulated in MATLAB using Simulink and Sim Power System set toolboxes, and different aspects of the proposed system are studied for various types of loads, and under varying wind-speed conditions. The performance of the proposed system is presented to demonstrate its capability of MPT, voltage and frequency control (VFC), harmonic elimination, and load balancing.

Permanent Magnet Generators for wind systems are an integral part of the overall system, converting the mechanical energy from the turbine into electrical energy. But since wind is an inconsistent source of power, the generator must be able to adapt itself to power fluctuations, such as excess or shortage of load. Furthermore, standalone wind systems are provided with batteries which must be kept charged under all conditions when the power is available. Thus, a controller is necessary for wind generator to adapt itself to these fluctuations.
